Rerailing a Flatcar in 1 to 1 scale?
Here is a KRL #300302 flatcar that appears to be de-railed. Quite likely the problem was that the rail shifted on the ties due to the heavy load.
Photos show car #300302 and O scale model.
I have the same problem at times with my O scale model when I want to place it on the track. The model is a 12-axle O scale KRL #300360 depressed center flatcar.
